Abstract

This study presents a multi-agent reinforcement learning (MARL) framework for integrated real-time control (RTC) of urban drainage systems (UDSs), coordinating sewers, wastewater treatment plants (WWTPs), and receiving waters. Trained within a hydraulic–water quality simulation environment using QMIX, the framework enables facility-level decision-making and adaptive system coordination. Applied to Lu’an City, China, MARL achieved a 25.4% reduction in flooding and overflow volumes and an 18.0% decrease in river pollutants relative to benchmark strategies, while maintaining real-time control feasibility (6.35 s per 5-min interval). Under rainfall forecast and sensor noise uncertainty, MARL improved performance stability by 44.7–52.4%. Despite operational trade-offs, the framework supports integrated system optimization and consistent water quality improvements in urban settings.

城市排水系统基于污染的综合实时控制:多智能体深度强化学习方法
本研究提出了一个多智能体强化学习(MARL)框架,用于城市排水系统(UDSs)、协调下水道、污水处理厂(WWTPs)和接收水的集成实时控制(RTC)。在使用QMIX的水力水质模拟环境中进行训练,该框架可以实现设施级决策和自适应系统协调。应用于中国六安市,与基准策略相比,MARL在保持实时控制可行性(每5分钟间隔6.35秒)的情况下,实现了洪水和溢流量减少25.4%,河流污染物减少18.0%。在降雨预报和传感器噪声不确定的情况下,MARL将性能稳定性提高了44.7% - 52.4%。尽管存在运营上的权衡,但该框架支持综合系统优化和城市环境中持续的水质改善。
